Ryzen 7 3700x running HOT

So I just recently made the transition form Xbox after 10 years and built my first PC. I've been having some cooling issues with my cpu. I have a 3700x with an H100i rgb platinum. My case is the corsair crystal 280x. I'm also running a 5700 xt Red devil. I have been experimenting with different fan placement. 6 120mm fans in total. 2 in the front as intake, 2 at the bottom as intake blowing fresh air onto the gpu, and i initially had 2 at the top as exhaust which was where I also had my 240mm radiator(the only place it will fit). Under full load my gpu is hitting a cool 68°C while my cpu keeps hitting 85°C under full load and throttling back a little bit. I had the autoboost on in ryzen master so it shoots it up to 4.4ghz when it can but the throttles to about 4ghz. I tied making the top fans with the radiator intake and making the bottom exhaust and my temp for cpu barely even moved while my gpu when up to about 82°C. So I switched them back and then I tried making all six of my fans intakes being that my case has a back grill thats more or less open and you can't mount a fan there. With all fans as intake my gpu cooled down to 68°C while my cpu is slightly better than initially but still hits 85°C. What can I do to get my cpu temp down to where it doesn't throttle? I want to overlook it and from what I've read and seen online, a 240mm AIO should be enough to keep a 3700x cool enough to not throttle with its rated boost clock. And in a case like the crystal 280 is it OK to have all fans as intake and then pressure just blows hot air out of the back? I really like being able to see my LL120 fans through the top glass but I will set them up as exhaust if I have to.

might consider going in and redoing the thermal paste. also, possibly bad water cooler, do you have a stock cooler to swap in to compare?

 

edit: also, welcome to the superior world of pc gaming lol. great build, especially for a first.

I do have the wraith prism that I can thrown on and see how it runs to compare.

It would appear, but correct me if I'm mistaken here...., that the entire case heat is exiting through the Cpu radiator.

You may want to exhaust some of that case heat out the back there instead of all of it through the cpu rad.

Sorry if that's not how this is configured, I can't tell the orientation of the fans...

Are you throttling during gaming or stress testing?

 

I recommend doing a manual voltage set and possibly OC.

Tier lists for building a PC.

 

Motherboard tier list. Tier A for overclocking 5950x. Tier B for overclocking 5900x, Tier C for overclocking 5800X. Tier D for overclocking 5600X. Tier F for 4/6 core Cpus at stock. Tier E avoid.

(Also case airflow matter or if you are using Downcraft air cooler)

Spoiler

 

Gpu tier list. Rtx 3000 and RX 6000 not included since not so many reviews. Tier S for Water cooling. Tier A and B for overcloking. Tier C stock and Tier D avoid.

( You can overclock Tier C just fine, but it can get very loud, that is why it is not recommended for overclocking, same with tier D)

Spoiler

 

Psu tier List. Tier A for Rtx 3000, Vega and RX 6000. Tier B For anything else. Tier C cheap/IGPU. Tier D and E avoid.

(RTX 3000/ RX 6000 Might run just fine with higher wattage tier B unit, Rtx 3070 runs fine with tier B units)

Spoiler

 

Cpu cooler tier list. Tier 1&2 for power hungry Cpus with Overclock. Tier 3&4 for overclocking Ryzen 3,5,7 or lower power Intel Cpus. Tier 5 for overclocking low end Cpus or 4/6 core Ryzen. Tier 6&7 for stock. Tier 8&9 Ryzen stock cooler performance. Do not waste your money!

Spoiler

 

Storage tier List. Tier A for Moving files/  OS. Tier B for OS/Games. Tier C for games. Tier D budget Pcs. Tier E if on sale not the worst but not good.

(With a grain of salt, I use tier C for OS myself)

Spoiler

 

Case Tier List. Work In Progress. Most Phanteks airflow series cases already done!

Ask me anything :)

Initially I had the 2 rad fans as exhaust and the other 4 as intakes. I then i swapped the 2 at the bottom to be exhaust and the rad fans and intake. It didnt really even make a difference with the cpu temp but my gpu temp suffered. I the swapped the 2 at the botton to be intakes to blow fresh air in the gpu, the rad fans are intake, and my front fans are also intake. So having all fans positive pressure pushes all the hot air out of the back. Whether that's more efficient than having 2 dedicated exhaust fans, idk.

it does throttle under stress, I'm gonna try and manually mess with stuff

The Corsair Crystal 280X is a poorly designed case to start with.

It has solid glass panels at the FRONT and TOP RESTRICTING airflow.

You basically have tiny slits / ventilation on the sides for the cool air to intake from the front, and exhaust out the top.

 

How are your temperatures if you REMOVE the side and/or TOP glass panel?

Do you see a significant CPU temperature drop?

 

If you do, then airflow is the cause of the problem -- or is part of the problem.

I had great luck undervolting and OCing my 3600. I run 4.2ghz all core @ 1.17V for F@H etc to keep temps down (55C or so) and I've been stable at 4.4ghz all core @ 1.32 gaming (56C is the highest I've seen, usually lower) but I'm not stable above 4.35ghz for F@H, blender etc with a voltage I'm comfortable with.

So I did take all panels off and it did make a difference. Not a big one though, roughly 4 or 5 degrees. However I did do a manual voyage set and OC and I got all cores to 4.2ghz at 1.225v and Temps will all panels on under stress don't exceed 78c usually sits at 77c most of the time. That's a lot better than what it was. When I set it to the auto precision boost Ryzen master was wanting to run the chip around 1.4v +/-.5v at only 4.1-4.2ghz boost. Thats why my temps where so high.

Honestly, even though the case has glass panels, there is a relatively significant gap around all of the panels. It really dosent make much difference with all panels on vs off. I feel that if you have 6 fans in it, it defenitly has adequate airflow.
